[lwip-users] Microchip ENC28J60 port?

[Andy Hewitson]

Hi,

 

I’ve settled on lwIP for the TCP/IP stack for an embedded project based on M32C87 (32 bit version of the popular M16C family by Renesas), using the uc/OS (by Micrium) real time kernel.  I have located an lwIP port for uc/OS.

 

I’m now searching for an lwIP device driver for the ENC28J60 Ethernet controller from Microchip.  Does such a thing exist?  I have seen posts of the same interest in archived mail, but nothing conclusive.

 

Thanks in advance

Andy Hewitson

I have bought one of these:

and am planning to write a device driver for it, on a STM32 (ARM Cortex).

I first need to wire it up and get some time. :-)

The low-level code which can transmit packets is now complete.
Next up is the device driver for lwIP now, against CVS HEAD.

I will not release until it is working, unless people want to test along.

Hi,

I have done that for the PIC32. It's a mod of the Microchip provided
driver for lwIP 1.3 and FreeRTOS. It's available in the svn
respository for VSCP (http://www.vscp.-org/download (m2m
firmware/pic/sweetbox) and also at the pic32 site

Thanks, that code looks pretty complete. I hadn't gotten to all the
errata yet, sigh... :-/

For quick reference, I was looking at your driver here:

http://m2m.svn.sourceforge.net/viewvc/m2m/trunk/firmware/pic/sweetbox/project/enc28j60drv/enc28j60.c?revision=275&view=markup

I'll continue to work on my driver, as I want to multi-thread it
eventually, removing all busy-waits, so I need to understand what
happens.
